OTTO A. BELGER, OF BOSTON, MASSACHUSETTS.

WASTE-COLLECTOR FOR COMBIN'G-MACHINES.

To all whom it may concern Be it known that I, O'rro A. BELGER, a subject of the Emperor of German Y, and a resident of Boston, in the county o Suffolk and State of Massachusetts, have invented certain new and useful Improvements in VVastcCollectors for Combing-Machines, of which the following is a specification.

Iyhis invention relates to combing machines of the character set forth by the Roth United States patent, No. 905,233, dated December 1, 1908. In said machine are combined a combing member, a stripping member coperating therewith to remove the waste therefrom, a casing inclosing those parts of the .combing and stripping members which are in Contact with each other, means foi-,creating a forced draft through the casing in a direction to take ed' the' waste from these members, a rotating perforated screen situated within the casing at a point between the stripping member and the exit of the casing and moving in such manner as to carry the waste arrested to\a point out of the range of the 'forced draft, and a stationary shield on that side of the screen to which the draft passes and covering a portion of the screen so\ that. the draft cannot pass through the screen at thispoint and consequently the waste is released therefrom.

The object of this invention is to provide certain improvements in the waste .collecting,r and removing portions of a combing machine of this character, whereby a plurality of combing and stripping members are cnabled'to cooperate with a single elon- -gated perforated screenmthe latter forming a portion of an air conduit extending from the combing and stripping members to air exhausting means, and the said conduit including a fixed member which supports the inner ends of the rotary screen and of the shield, and is adapted to be connected with air exhausting means such as an exhaust fm1, said fixed member and shield forming anhu obstructed air passage which enables air to be exhausted simultaneously from a pumber of combing and stripping members y a single exhaust fan or other like ap- Of the accompanying drawings z--Figure 1 represents a side elevation showing somewhat diagrammaticall the back side of a combing machine havinga waste collector embodying my invention.

a diagrammatic section on `line of Fig, f

1. Fig. 3 represents a longitudinal section oit' the waste collector shown by Fig. 1, parts sheet metal and having at its outer end a practically closed head 13 rovided with a central liournal 14 to whici is attached a gear 15.

16 represents a fixed stud or bearing which rotatatively supports the journal 14 of the tube 12.

17 represents a fixed air conduit member` which 1s preferably approximately T-shaped, n

the body portion of said member' bein cylindrical and provided with a latera flanged branch 18 adapted to be coupled to a pipe 19 leading to the casing of an exhaust fan blower, not shown. The member 17 is provided with an internal annular bearing 20 which receives the rotatively supports the inner end of the tube 12, said inner end being preferably reinforced by a peripheral ring 21 constituting a journal in movable contact with the bearing 20.

The tube 12 is provided with a plurality of perforated zones 12 which are separated as shown by Fig. 1 by imperforate portions of the tube, sald zones being spaced apart and coinciding with casings D which correspond in number with the perforated zones. each casing inclosing a combing inember A and a stripping member B. Said members and the casing D may be con structed and adapted to cooperate in the manner described in the Roth patent. above referred to. Each casing has an outlet which is formed as indicated by Fig. 2 to receive a portion of the periphery of the tube 12 so that air drawn inwardly into the tube through its perforated periphery will create a forced draft in the casing and carry waste from the members A, B, to' the perforated zones of the tube 12.

A23 represents an elongated tubular shield located within the tube 12 and concentric therewith, said shield being provided with Fig. 5 represents openings 24 which permit air impingiiig on the outer periphery of a perforated zone 12 to enter the shield at one side thereof, so that Waste carried by the air is caused to adhere to the portion of the perforated zone coinciding with the opening 24.

The rotation of the tube 12 continuously removes the collected waste from a point opposite the opening 24, the removed waste being no longer held by atmospheric pressure against the perforated tube and being condensed into a fieece or sliver 26, Fig. 2, by means such as a pressure roll 27 arranged as shown by Fig. 2.

The operation of the machine so far as the collection of thewaste into a fleece or sliver is concerned, is the same as that described in the above-mentioned patent to which reference is madeor a fuller description.

The outer eni of the shield 23 is provided with a spider 28, the hub 29 of which is rigidly attached to the center bearing 16. The inner end of the shield 23 is open and unobstructed and projects from the inner end of Lhe tube 12 into the fixed conduit member 17. Said member is provided within the bearing 20 with an annular internal seat 30 in which the inner end of the shield 23 closely lits and to which said end is fixedly secured b v any suitable means preferably screws 32 passing through slots 33 Nin the shield. The slots `and screws 32 permit the shield to be adjusted to bring its openings 24 into suitable relation with the outlets of the casings D.

It will now be seen that air exhausted from the conduit member 17 through the pipe 19 will cause a forced draft of air from the combing and stripping members through the casings D, the tube 12 and the shield It will also be seen that the described construction enables the inner end of the shield 23 to be left entirely unobstructed and provides an unobstructed air passage through the fixed member 17 so that a single air cxhausting fan or other apparatus is adapted to draw waste from a relatively large number of combing and stripping members, the air current set up being t'ully utilized owing to the absence of obstructions in the inner end of the shield and in the interior of the fixed member` 17.

Prior to my invention, a waste collector of the construction shown by Figs. 6, 7 and 8 has been employed. 'ln this prior construction, the fixed conduit member 17?- is provided with an inwardlyr projecting bracket 3:7 which supports the inner end of a stud 37. The elongated perforated tube 12 projects into the fixed member 17 and is provided at. its inner end with a spider 38, the hub of which forms a journal rotating on the stud 37. The inner end of the shield is provided wth a spider 39, the hub of which is fxediy scoured on the stud 37.

It will be seen by comparing Figs. 3 and 6 that my improved construction eliminates all obstructions of the inner end of the shield and of the interior of the fixed conduit member. To prevent the formation of a dead air space at the outer end of the tube 12, I provide the head 13 with small air passages 40, Figs. 3 and 5, adapted to permit the entrance of a limited quantity of external air. The air thus admitted-prevents a body of stagnant air from remainin in the outer end portions of the tube 12 and shield 23, and therefore prevents the waste from settling, accumulating in said outer end portions and eventually clogging the adjacent shield opening 24.

The described construction is preferably Y duplicated at each end of the fixed member 17, both ends of said member being open, and said ends being formed to support the inner ends of two tubes 12 and two shields 23. lt is obvious however that one end of the fixed conduit member 17 may be permanently closed it' the construction of the carding machine renders this desirable,

The fixed conduit member 17 may be provided with a handhole 42 and with a cover 43 itierefor. Figs. 4 and 5 show the fixed member 17 provided with a slotted ear 44 attached by bolts to supports 45.

The perforated zones of the tube 12 constitute multiple screens which are connected in a series by the imperforate portions of the tube. f
